PAPER FEEDING.

Application filed August 7, 1924:.

My invention relates to improvements in paper feedin'. It relates particularly to the feeding of single sheets of paper from a pile, in the operation of feeding sheets to a ruling machine, printing press or the like.

@ne of the objects of my invention is to provide a. novel method of detaching and withdrawing the outer sheet of a pile of paper, which method is adapted for sheets of all sizes and for the rapid feeding thereof from the pile.

Another'object of my invention is the provision of novel means for reliably separatingand partly detaching the outer sheet fromuthe pile.

A further object of my invention is the provision of novel means for engagement of the partly detached sheet adjacent to a corner portion thereof and carrying the detached sheet forwardly with its sides reversed, whereby the sheets in being fed may overlap each other, thereby permitting a maximum speed of operation, without interferingg; `with Athe propertiming of the sheets, :is tl ey are delivered to the ruling machine, printing press, or folding machine.

A further object of my invention is the provision of novel means by which the detached sheets are brought into proper1 register'.

Still another object of my invention is the provision of novel means for raising the pile of paper automatically, as the sheets are fed therefrom.

Still another object of my invention is to provide a paper feeding machine of t-he kind described, which is relatively simple, which isdurable, notliable to get out of order, which is readily adapted to be used in connection with ruling machines, foldingl machines and printing presses.` which are now in use, which reliably detaches single sheets from the pile and brings them into proper register, and which has a .maximum speed of operation.

The novel features of my invention are hereinafter fully described and claimed.

:he eccentric .is revolved with the 'dei shaft 12, the bar raises and lowers the tube 44, thus rocking the shaft 238. The oscillation of the latter is limited in one direction by the bolt 43 striking the frame 1, Fig. 7, and the movement of the rock shaft in the opposite. direction is limited by the tube 44 striking the collar 40. The stroke of the bar 45 is such that it continuesits upward movement in the tube 44, after the latter has contacted with the collar 40, and the bar 45 continues its downward movement after the bolt 43 strikes the frame 1.

In the operation of the machine, when sul'licient sheets have been fed from the pile, to require the table to be lifted, the shoe 39 will not be obstructed by the pile, so that the bar 45 will move the tube44 so as to rock the shaft 38 to a position in which the collar 35 will strike and pull down the arm 33, thereby rocking` the shaft 31 so that the bar 3() will swing in a direction which lowersthe pin 29 enough to permit the pawl 19 to engage the ratchet wheel Ell). rlihe eccentrics 13 and 417 are so disposed relatively to each other on the shaft 12, that the shoe 39 will be slightly in advance of the pawl 19, that is the shoe 39 will have begun to lift from the pile of papers as the pawl reaches the limit of its movement to the left, as viewed in llig. 5. is the shoe 39 rises, the pawl 19, when dropped `so as to engage the ratchet Wheel, will beturning the ratchet wheel Q0 so as "to lift the table, as above den scribed. lJlhen the shoe is moving' downward toward the pile, the pawl 19 is being retracted over the ratchet wheel 9.0. As long;` as the top of the pile 3 is below the predetermined level, shown for example, in liig. 4, the pawl 19 will be engaged lwith the ratchet wheel 20, thereby eli'ecting,l lifting of the table 2. When the top of the pile again reaches the proper height, the pile i will resist the downward n'iovement of the shoe 39, so that the collar 2lb can not pull down the arm 33, and the spring. 32 will swing` the bar 3() so that the pin 29 will lift the pawl 19 and hold it disengaged from the ratchet wheel, at which the liftiiip; olf the table will temporarily cease.

The. frictional engagement of the bar -l-. and the tube 44 is so adjusted that the bar will slip in the tube when the pile holds the shoe from making its full stroke dcnvnwardly. The tric-tional engagement is such as lo overcon'ie the strength of the spring lo enable the bar to force upwardly the tube 44, so that the collar 35 can move the arm 33 downwardly, to permit the pin 21 to allow the pawl 19 to engage the ratchet wheel.

For separating the outer sheet from the pile and for partly detzuthingl the ,separated sheet from` the pile, suction means is provided which lifts and carries the top sheet. Such means may comp 'ise a suction cylinder 48 supported at its upper and lower ends by a bracket 49 fastened to the frame 1. '.lhe cylinder 48 is oscillatively mounted on an anis oblique to the top of the table 2, and is provided at one side adjacent to its lower end with a tubular suction arm 50, which is swung by the cylinder 48 back and forth between the positions shown in Figs. 1 and 11. The inclination of the axis of the cylinder 48 is such that as the suction arm 50 nieves from its rear position, shown in Fig. 1 toward the forward position, shown in Fig. 11, the mouth of the suction arin will rise from Contact with the pile of paper, and will move in an arc and will lift and carry forwardly and laterally the top sheet. of the pile. j

lo create suction in the cylinder 48 and arm 50, there may be slidably litted :in the cylinder 48 a piston 5l attached to a piston rod 52 slidable through the upper head of the cylinder, lilig'. 10. rlhe upper end of the rod 52 is connected by a universal joint 53 with a linlr 54, the upper end of which is pivoted to a cranlr arm 55 on a rock shaft 56, which is a sleeve oscillatable on the frame 1. llhe rocli shaft 5G has a crank arm 5'2" extending oppositely to Vthe cranlr 55, to which is pivoted the upper end oi a bar 58, the lower end of 'which is attached to a strap 59 which em# braces an eccentric G0 secured to and rotar.M able with the shaft l2.

.For oscillating the cylinder 48 on .its airis, itl-ias extending; laterally from it a bolt (il, rig. 1l), on winch is pi voted a collar 6:2 having oppositely extending pins lill on which is pivoted the bi'lurcaled end of a link (54, Fig, 5.

The linl; U4 is pivoted on a bolt 65 on which is also pivoted the adjacent ends of a link 66 and the upper end of a bar (Si. 'llhe linl; GG is pivoted to the frame l, and the lower end of the bar G7 is attached lo a strap 68 which embraces an eccentric 69 secured to and rotatable with the shaft lil.

ril`he cccentries G0 and (59 are so disposed on the shaft 1Q, that the piston 5l, has started on ils upward suction nu'ivement when the siA :tion arm 5U is at its rear position on the pile, as shown in liip'. Thus, when the suction arm starts on its VForward movement from the position shown in 'l'iilut 5, it will have sucked and is holiflinn the top sheet, as the cylinder Liii swings the arm 5l) forwardly. he arm 5U will ther. carry the top sheet forwardly and laterally uulil the advanced corner portion of the sheet is `gripped by the mechanism Awhich carries the sheet from the pile and carries it to the regristerinpj mechanism. its the eccentric is disposed in advance of the eccentric (it). the suction eti/'ect in the cylinder and arm will cease before the suction arm reaches its most forward position` thereby releasing the sheet. which at the time will have been seized by the carrying oli mechanism. On

lli

the downward movement of the piston 51, air will be blown from the arm 50. rlhe upper' end of Vthe `cylinder i8 has openings for the admissionuof air on the down stroke, and for the expulsion et air on the upstroke ot the piston 51.

rllhe suction arm 5l) is disposed so as to pass later-ally oil' Ylroin the pile at its lorward limit, and it can then pass ruuler the sheet 'which just being detached by the carrying mechanism.

. For carrying the ylop sheet 'from the pile, and reversing it, the following described mechanism is provided.

Referringparticularly to Figs. l, Ll, (i, 7 and 1 1, 71 designates a transverse roller disposed horizontally at the lett ot and slightly oblique vto the lett edge otI the table Q, as viewed in said ligures. .ll belt 7E?. ein- "braces the roller '7l and a roller 'ill at `the right ot and higher and parallel with the roller 71. The latter is rotatably mounted in the frame 1, and may be connected by other belts 74, Figs. 1 and '11, with the roller 73.

Above the roller 73 and parallel therewith is a shaft 75, which is rotatably mounted in two brackets 76 and 77, Fig-s. 1 and 11, snpported on the trame 1. Secured to and ro- Ltatable with the shaft 75, is a roller 78, on

which is mounted a belt 79, disposed above and parallel and in contact with the belt 72, and which bears against the belt 72 at the left and under side ot the roller 71, and which is mounted upon a small roller 80, Figs. Il and 7, which is disposed parallel with the roller 71 below the latter and between the latter and the pile 3. 'Ehe belt 79 also passes over two rollers ill and SQ, rotatably mounted on a bracket 83, Fig. 3, which is supported on the 'traine l. lin arcuate bracket 84e has its convex upper side extending` between the rollers 71 and 73 and holding` the upper po-rtion of the belt .72 against the adjacent portion of the belt 79, Figs. el, 6 and 7. rlhe bracket S/l is supported by the frame 1.

lhe suction arm 50 carries the top sheet forwardly, and owing to its swinging' movement, and to the disposition ot the rollers 71 and 8O slightly oblique to the adjacent edge otthe pile 3, and owing` also theisuction arm 50 engaging the sheet adjacent to the most advanced corner thereo't, the corner portion ot the sheet .tirst enters `between the belts 72and 79, Figs. 6, 7 and 9, and is gripped by and between the belts, and is carriedotl' trom the pile 3 with its sides reversed. This reversal o1 the sides el the sheets, is to enable them to overlap each other, as shown in Fig. 11. the last sheets as they are-being ted lyingon top ot those iinmediately preceding. The overlapping ot the sheets in this manner does not interl'ere with the action ol the tuningmechanism ot the machine to which the slufets arr` heiiulf fed, such as the gate oil? the. ruliugi nnufhine, and it enables tast operation lio he ellected.

The rollers 73, 94 and 95 being oblique to the guide groove 97, and having their upper sides moving toward said groove, will carry the sheets forwardly, and at the saine time laterally to the guide 96.

In order to hold the sheets against the upper sides of the rollers 951., 95 and 86, and also to assist in moving the sheets laterally toward the guide 96, there may be provided `flexible nienibers comprising, preferably, chains 99 which rest transverse] y across and upon the rollers 9d, 95 and 86 and have one set. ot ends respectively atl ached lo two rollers 99, which are respectively rotatably mounted on two plates 100 which are respectively secured to the brackets 76 and 77, see Figs. 1, 6, 6 and 11. One oit' the rollers 99 has its periphery bearing against onel end ot a roller 101,`and the other roller 99 has its periphery bearing against one end of the roller 78.

The rollers 7 6 and 101 in revolving, re volve the chains so that the under sides of the latter move toward the `cuide 96, thus moving the sheets,` which are :Fed between the chains 98, and the rollers 911- aud 95, toward the guide groove 97.

Each of the rollers 73, 94 and 95 has its end which is next adjacent to the guide 96 supported by the following described mechanism. Referring particularly to Figs. 12 and 13, which illustrates the support tor the roller 94E next adjacent to the roller 88, 1.02 designates a ring fitted in the end oi the roller nent adjacent the guide 96. Mountedt in the ring 102 are two diametrically opposite pins 1.03 on which is rotatably mounted a connecting member 104 through which eX- tends a pin 105. A horizontal shaft 106 is rotatably mounted transversely in the frame 1, and has a bifurcated inner end, the arms ot which respectively embrace opposite sides of the connectingl member 10i, the pin 105 being mounted in the said arms oi the .shaft 106. A universal joint connection lis thus effected between the shat't 106 and the adj acent roller which it drives.

For rotating all ol the shafts 106 in like directions, so as to rotate the rollers 7?), 94. and 95 in the proper direction, said shafts 106 have respectively secured to and rotatable with them pulleys 107. A. driving `belt 108 embraces a pulley 109 secured to the sharit 93. The belt 106 also enibraces the upperand lower` sides oi'l the pulleys 107, Figs. 1,2 and 12. rllensioning;r pulleys 110 rotatably mounted on the traine 1 bear at intervals against the lower portion ot the belt 108, so as to hold the latter in driving contact with the dilierent pulleys 107 and 109 with which the belt engages.

ln the operation of the invention, the pawl 27 is disengaged from the ratchet wheel 20, and the crank 26 is turned so as to lower the table. The pile of paper is then inserted on the table, with lhc forward edges ol the sheets against the guide bars 11. The pawl 27 is then permitted to again engage the ratchet wheel 20, and the crank 26 is turned to wind the bands 25 ou the sha'lt 241: to lii'it the table to a position in which the top sheet will be about level with thc center oi the roller 60.

The power is then applied lo operate the ruling' machine 66 and to rotate the shaft 12. This `vill ell'ect rotation, by means ot the inechanisni alrcaily described oli the rollers 73, 94, 95 and The belts 74; and the belt 72 will eti-ect rol ation oi? the roller 71 and the belt 72 will drive the belt 79.

The shailit l2 will eill'cct rotation of the eccentrics a7, 60, 1 3 and 69. These eccentrics will respectively operate the shoe and pawl liftingl means, the piston 51, oscillate the pawl 19 and oscillate the suction cylinder 46. The latter in oscillating will escillate the suction arm 50, and the latter will pick up a sheet and carry it forwardly into and between the belts 72 and 79, by which the sheet will be gripped and carried 'forwardly i'rom the pile with one corner in advance. lhe belts 72 and 79 will reverse the sides ct the detached sheet, and will deliver the sheet between the chains 98 and the rollers 94C and 95, and with one longitudinal edge of the sheet adjacent to the guide 96 parallel with the guide.

The rollers 94 and 95, and the chains 96 will cause the sheet to be moved laterally into the groove 97, and the rollers will at the same time carry the sheet forwardly to and between the rollers and 87 ot the ruling* machine 66. The groove 97 will hold the sheet arched. rlfhe taperingrollers 95 in addition to carrying the sheets forwardly tends to retard the moif'ement ot that edge portion ot the sheet next adjacent to the small ends ot the rollers, as the periphery o'f each tapering;v roller travels slower at the small end. than at its large end. This prevents light sheets being buckled due to the pressure to which it is subjected against the guide 96.

llVith every 'ljor 1ard movement ofthe suction arm 50," the shoe 69 is lit'ted from the pile to pernlit the separated sheet bein,r withdrawn lroin the pile, and at ea ch return u'ioveincnt ot the suction arm 60, the shoe 39 is again luought down on the pile.

When the top oi the pile ot' paper lowers sutliciently, the shoe will be permitted to lower to a point where the collar 35 engages the arm 33, and rocks the shat't 31 so'tllat the pin 29 will permit the pawl 19 to engage the ratchet wheel 20. The eccentric 13 in effecting oscillation forwardly and backwardly of the pawl 19, will cause the latter to ettect step by step rotation of the ratchet wheel 20, until the table has been lifted to raise the top of the pile to the posilitt? fl,

tion shown in lTig. il, at which time, the pile o'l' paper will reeiet the downward niorenient ot the shoe 39, and the bar t5 will slip in the tube 44, so that the rook elia'tt 38 will not roek sn'llieiently to censo the collar 35 to swing the arin 33 to perinit the pin 29 letting the pawl ll) engage the ratchet wheel 20, and the liftingl ot the table 2 will he dieeontinned nntil the top et tlie pile has again lowered enough to permit the pawl ll) to again engage the ratchet wheel 20.
